According to Simonnot G, 2016, the site position is ETRS89 0402240 4792288.

The information has been roughly translated from the French, Spéléo-Club de Dijon reference, Degouve de Nuncques Patrick et Simonnot Guy, 1989 (in Sous le Plancher, no 4, 1989), repeated and continued in Simonnot G, 2016. The French reference number for this site is SCD2012.

On the fold of Llaneces, two hundred metres to the east of the path suitable for motor vehicles which reaches that point. Explored by the SSB in 1965 and the SCD in April 1982  when it was surveyed.
Two sections of short galleries are intersected with pitches  (p14; p7; p11; p5)  which drop down to -86m and a large, inactive gallery which goes from southwest to northeast for nearly three hundred meters.
At the southwest end (-98) crawls are usually occupied by very thick clay fillings.
In the 2010, the narrow section at -98m was excavated and passed into 145m of passage, explored and surveyed in 2014.
